Beyond fleas, ticks and mites (see separate topic), your dog may have an allergy—to plants or food, or insects other than fleas and mites. It may have dry skin, bacterial or yeast infection or more serious conditions such as hypothyroidism, an autoimmune or immune disease, cancer, mange and Cushing’s syndrome just to name a few…the list is long. If your dog is getting hot spots, sores or losing hair, see your vet. Diet, making sure your pet does not have a parasite (fleas, ticks, etc), and bathing your dog in cool water, careful drying, and a cool dryer will possibly calm it down. It is persists, check with your vet—there are a great number of potential causes.
